产品描述

- Commodity name: DG-LMCRTU Side-Mounted Water-Collection Remote Terminal Unit
Measurement principle

The product employs a composite measurement technology that integrates ultrasonic, hydrostatic, and conductivity sensors, leveraging the complementary strengths of multiple sensing modalities to significantly enhance the accuracy and reliability of road‑water‑accumulation detection. Mounted on curb stones, the device requires no complex installation work, enabling rapid deployment and straightforward post‑installation maintenance, thereby effectively reducing labor and time costs and providing an efficient, stable solution for urban road‑water‑accumulation monitoring.

Key Features

Measurement parameters: water level, electrical conductivity, temperature, and signal strength.
NB‑IoT model: 0–0.5 meters (under the condition that the signal strength is better than −80 dB after installation)
LORA RF model: 0–2 meters (requires a dedicated signal concentrator)
2 mm stainless steel reinforced housing, with a 45° chamfered angled impact‑resistant contact surface.
Ultrasonic, hydrostatic, and six-channel electrode-type multimode composite sensor
Built-in integrated dedicated antenna
Fast installation, reduced operational costs
Quick installation of curb side walls (using two M8 expansion screws and a socket wrench)
It features a relatively concealed installation, minimizing its impact on the landscape.
Both the NB and LoRa models support remote OTA.
All parameters support remote configuration.
Equipped with the Ping An Reporting feature.
Has obtained multiple patents and software copyrights.
Built-in automatic atmospheric pressure self-balancing algorithm

Application scenarios

Measurement and early warning of waterlogging on municipal roads, park pathways, and critical infrastructure (such as electrical facilities like transformers, machine stations, substations, and charging stations).

Installation location: roadside curbs and other facade conditions; side-mounted installation.

Important Note 1: When using NB‑IoT for direct wireless data upload, be sure to verify the strength and stability of the NB‑IoT signal at the installation site, as these factors may affect the reliability of data transmission. If you cannot confirm the quality of the NB‑IoT signal, we recommend opting for the more robust transparent‑transmission LORA RF model. By default, the NB‑IoT version is configured to use the China Telecom network.

Important Note 2: When installing on curb stones, ensure that the device is not placed in areas where vehicles may park on the side, to avoid damaging vehicle tires and other components.
